First by phosphonitrilic chloride polymer nitrile tetrahydrofuran solution, slowly drip in the reacted there-necked flask of step S3 by constant pressure funnel, after dropwising, continue stirring 1��2 hour;
Again by intermediate product solution (II), slowly drip in the solution after stirring by constant pressure funnel, after dropwising, continue stirring 2��3 hours, obtain reaction solution.
